QADC64E Legacy Mode Operation
channel field of the conversion command word (CCW) table. External Multiplex mode is software
selectable, by setting the EMUX bit of control register 0, QACR0.
Figure 13-3
The QADC provides three multiplexer address signals – MA[0], MA[1], MA[2] – to select one of the
multiplexer chips. These outputs are the multiplexer control lines and they are connected to all external
multiplexer chips.
The analog output of each of the four multiplexer chips is connected to four separate QADC inputs – ANw,
ANx, ANy, ANz. These signals are the first four signals of port B and each one can represent eight analog
input channels. The QADC converts the proper input channel (ANw, ANx, ANy, ANz) by interpreting the
channel number in the CCW. Refer to
In the external multiplexed mode, four of the port B signals are redefined to each represent eight input
channels. Refer to
